American Motorcycle Association v. Superior Court

Supreme Court of California
578 P.2d 899 (Cal. 1978)



Glen Gregos (plaintiff), a minor, was injured in a novice motorcycle race that was allegedly negligently organized and run by the American Motorcycle Association (AMA) (defendant) and the Viking Motorcycle Club (Viking). AMA sought leave to file a cross-complaint against Gregos’ parents alleging their negligence and improper supervision of their son. AMA also requested the damages assessed against it be reduced in proportion to the “allocable negligence” of Gregos’ parents. The trial court denied AMA’s request for leave, and AMA appealed.
